SPRING-LATCH FOR WI-IEELED SCRAPERS.

Specification of Letters Patent.

Patented Mar. 16, 1915..

Application filed January 28, 1913. Serial No. 744,681.

To all whom it may concern:

Be it known that we, HARRISON B. WAL- TON and JEFF M. Esrns, citizens of the United States, residing at Levee Camp, in the county of Tunica and State of Mississippi, have invented certain new and useful Improvements in Spring-Latches for lVheeled Scrapers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates primarily to wheeled scrapers, has especial reference to means for retaining the pan in position, has for its object a spring-latch which can be readily manipulated, and the invention consists in cer tain improvements in construction, which will be fully disclosed in the following specification and claim.

In the accompanying drawings, which form part of this specification :Figure 1 is a perspective of so much of a scraper as is necessary to illustrate our invention. Fig. 2 is a side elevation of the spring-latch detached, and Fig. 3 is an end view of the same.

Reference being had to the drawings and the designating characters thereon, the numeral 1 indicates the pan, 2, 3, the supporting bars, 4 the Johnson bar and 5, 5, the handles of a conventional scraper, and all of which are well known in the art.

6 indicates the spring-latch pivotally secured to the bar 4: at 7, provided with a latch 8 at its lower end to engage the catchbar 9 on the scraper, and with a lateral extension 10 in the outer end of which a spring 11 is secured by a set screw 12. The latch or hook at the lower end of the spring-latch is provided with an extension 13, which prevents hanging on the scraper or pan when loading the scraper.

The operation is as follows: Then the scraper 1 has been filled, the bar t is drawn down, which raises the scraper, and the latch 8 engages the bar 9, when the free end of the spring 11 bears against the un derside of the bar 4, as shown in Fig. 1, and holds the latch in engagement with the bar 9, until the load has been discharged, when the bar 9 may be released by the operator disengaging the latch by raising the end or lever 14:, when the scraper will descend for reloading.

Having thus fully described our invention, what we claim is:

In a wheeled scraper having a pan, a Johnson bar adjusted thereon, an angle bar pivoted to said Johnson bar, a catch on the lower end of said angle bar, a handle on the upper end of said angle bar, a latch, a catch bar on said pan engaged by said latch, a member extending laterally from said catch bar and a recurred spring extending from the outer end of said member and engaging against the under side of the Johnson bar.

In testimony whereof we afliX our signatures, in presence of two witnesses.
